ios - 视频播放器崩溃 pathForResource Swift iOS

Question

目前我尝试设置一个简单播放视频的小应用程序(只为我的女儿)，但它总是在“路径”上崩溃

import UIKit
import MediaPlayer

var moviePlayer : MPMoviePlayerController?

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        playVideo()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    func playVideo() {

        let path = NSBundle.mainBundle().pathForResource("video", ofType:"mp4")
        let url = NSURL.fileURLWithPath(path!)
        moviePlayer = MPMoviePlayerController(contentURL: url)
        if let player = moviePlayer {
            player.view.frame = self.view.bounds
            player.prepareToPlay()
            player.scalingMode = .AspectFill
            self.view.addSubview(player.view)
        }
    }

}

崩溃发生在这里 let path = NSBundle.mainBundle().pathForResource("video", ofType:"mp4")

fatal error: unexpectedly found nil while unwrapping an Optional value cause path is empty

您必须将 Build Phases 下 Xcode 目标中的视频添加到 Copy Bundle Resources。
